Ive got some troubles with upgrading drills and belts. Everything is good but belts and drills. Getting 'uncommon' and no longer updating with recommendation to put it in a blacklist. Manual replacement doing nothing: quality is still upgrading but without scaling any parameters (HP is an exception).
May be its incompatible with other mods.
New (upgraded) machines replaced by Quality Lib.
Following mods for belts and drills:
AAI Industry
Bob's Mining mod
Bob's Logistics
Matt's Logistics
Plus mods changing and/or working with quality:
Better Quality (Quality Lib is required)
Quality Effects
More Quality Uses
More Quality Utilities (sry, forgot about it)
